A partial solar eclipse will take place on Friday, July 13, 2018, but will only be visible in extreme southern Australia and Antarctica.

This eclipse belongs to Saros 117 and is number 69 of 71 eclipses in the series. All eclipses in this series occur at the Moon's ascending node. The Moon moves southward with respect to the node with each succeeding eclipse in the series and gamma decreases.

This is a very deep partial eclipse, NASA's Fred Espenak noted. It has an eclipse magnitude of 0.3365, while Gamma has a value of -1.3542.

The event begins at 01:48 UTC and ends at 04:14 UTC. The instant of greatest eclipse will take place at 03:01 UTC, 0.2 days before the Moon reaches perigee. The Sun will be in the constellation of Gemini.

Partial coverage of the Sun will be visible in parts of southern Australia, such as Melbourne (maximum magnitude of 0.022558) and Geelong (maximum magnitude of 0.031923) in Victoria; Mount Gambier (maximum magnitude of 0.045189) in South Australia, and Hobart (maximum magnitude 0.094527) and Launceston (maximum magnitude 0.072570) in Tasmania.

The eclipse will also be visible in Stewart Island in the far south of New Zealand.
